"The forebrain was removed from Tilapia mossambica, a cichlid fish that shows schooling behavior. The fish was tested in an optomotor apparatus before and after forebrain ablation. After ablation, there were significant decrements in fish r.p.m. in relation to drum r.p.m. and in the ability of the fish to reverse direction when drum direction was reversed. The relevance of these findings to schooling is discussed"--P. 15.
